Snorkeling and Diving Reopen in Phi Phi Islands Following Year-Long Environmental Closure

Authorities in Thailand have officially reopened ten popular snorkeling and scuba diving sites within Hat Noppharat Thara–Mu Ko Phi Phi National Park in Krabi Province. The reopening, which took effect on April 17, 2025, comes after a year-long closure intended to allow the area’s coral reefs to recover from significant bleaching. This decision marks a significant step forward in both environmental conservation and the revival of marine-based tourism in southern Thailand.

Coral Recovery Prompts Reopening

The temporary ban, which began on May 13, 2024, was implemented in response to widespread coral bleaching in the area. Coral bleaching occurs when elevated sea temperatures force corals to expel zooxanthellae—the colorful, symbiotic algae that live within their tissues. This process leaves corals pale, weakened, and highly susceptible to disease. Over the past year, authorities and marine biologists closely monitored the condition of the coral reefs, observing visible signs of natural recovery and regeneration, which paved the way for the reopening.

The ten sites near Phuket are now accessible to the public include the northern and eastern sides of Koh Gai (Chicken Island), the northern side of Koh Poda, Ao Pu Ya on Koh Poda, Koh Daeng, Railay Bay, Koh Yawasam, Loh Ba Gao Bay, Viking Cave, and the front of Pi Leh Bay. These locations are known for their crystal-clear waters and vibrant marine life, making them top destinations for snorkeling and diving enthusiasts. However, the western side of Koh Gai (Ao Khang Khao) will remain off-limits to continue safeguarding its delicate reef ecosystem.

In conjunction with the reopening, park officials have emphasized the importance of responsible tourism. Visitors are required to follow strict regulations designed to protect marine habitats. These include prohibitions on littering, discarding food waste into the sea, anchoring boats on coral reefs, and any physical contact with coral or marine animals. Violators may face penalties to ensure compliance and preserve the fragile ecosystem.

The reopening aligns with Thailand’s ongoing efforts to bolster its tourism sector following global travel disruptions. In 2024, Thailand welcomed over 35 million international tourists, generating more than 1.8 trillion Baht in revenue. The return of snorkeling and diving activities in the Phi Phi Islands is expected to attract even more visitors in 2025, supporting local communities and reinforcing the country’s commitment to balancing economic growth with environmental sustainability.
